Free Amazon Backend Keyword Generator
Describe your product and paste your current title. We'll generate a 250-byte backend search-terms string — synonyms, misspellings, alt names — with no duplicates of your title.
Three steps.
Zero friction.
- 01
Describe your product (what it is, key features, use cases).
- 02
Paste your existing Amazon title so we can skip those words (Amazon ignores duplicates).
- 03
Copy the string into Seller Central > Edit listing > Keywords > Search Terms.
The 250-byte field most Amazon sellers waste
Amazon's backend search-terms field gives you 250 bytes to index for keywords that DON'T appear in your title or bullets. It's the single highest-leverage SEO field on a listing — yet most sellers paste the same words already in their title (which Amazon ignores), use commas (Amazon ignores those too), or repeat brand names (also ignored).
The right play: space-separated single tokens, all synonyms / misspellings / alternate product names / use-case words your title can't fit. No commas, no quotes, no brand, no duplicates. Under 250 bytes (Amazon counts bytes, not characters — special chars can eat 2-3 bytes each).
